  • the seal shown in FIG. 10A essentially corresponds to the seal as shown in FIG. 7C, with a full bead supported by two rows 10, 16 of recesses 18, 22.
  • a row 200 of depressions 202 are arranged in FIG. 10, but they point in the other direction and here they do not support the back of the full bead, but instead support the base of the full bead so that it can move upwards.
  • the recesses 18 and 22 are pressed against the direction in which the full bead is formed in the position of the gasket to support it.
  • the recesses 202 are pressed against the direction in which the full bead is formed in the position of the seal to support it.
  • the depressions 202 are formed or pressed in the same direction as the full bead 6 in order to additionally support the root of the flank 10 of the full bead 6 in the opposite direction.
  • FIG. 10B shows a larger section of the seal from FIG. 10A, which is additionally provided with a "hinterland stopper.”
  • FIG. 10B further additional rows 200 of depressions 202 are arranged on the seal which do not lie between the flanks of a full bead 6
  • a plurality of recesses 202 arranged one behind the other and adjacently are arranged along a plurality of substantially parallel lines 200.
  • the region 204 may be surrounded by a half bead and extend, for example, between two bolt holes 210.
  • the depressions on adjacent lines can each be staggered relative to one another, whereby the individual indentations can fill a surface on a layer of the metallic flat gasket, which in principle is arbitrary can be shaped. It is also possible to arrange the rows 200 of recesses 202 along a curve.
  • seals shown in Figures 2 to 6 can be made with a tool that can be manufactured in large part on a lathe.
